Scientists at the U.S. Geological Survey are closely watching the long, thin barrier islands that comprise the Gulf of Mexico coast of west Florida as Hurricane Ivan approaches. These islands are particularly vulnerable to storm surge and coastal change during hurricanes because of their low elevation. New elevation maps show just how vulnerable.
“If Hurricane Ivan comes ashore on west Florida’s barrier islands as a major hurricane, Category 3 or stronger, most of the coast has the potential to be inundated by storm surge under the south eye wall at landfall,” said Abby Sallenger, a USGS oceanographer.
The USGS and NASA recently surveyed these islands using airborne laser mapping, providing for the first time detailed elevation maps of the island’s ‘first line of defense.’ An example of the ‘first line of defense’ would be a sand dune protecting an ocean front cottage or road. The average Florida west coast ‘first line of defense’ elevation is about 6 feet -- less than half the 13-foot average of the Florida east coast where Hurricane Frances made landfall a week ago.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
